Maximum values for send and receive bytes
The Suconet K protocol allows data with a variable
length to be transferred cyclically, whereby the
number of bytes is dependent on the settings for the
master and the slave (see below). The data length for
communication with slaves for expanding the remote
inputs/outputs is dependent on the slave type. With
intelligent slaves you can specify the number of send
and receive bytes yourself. However, the following
maximum values must not be exceeded:
Table 4: Maximum values for send and receive bytes for the
PS4-200
* For certain configurations, the number of
send and receive bytes can be increased to
256 (see Appendix).
Send/receive bytes Master Slave
Max. no. of send bytes (output) 128 78
Max. no. of receive bytes (input) 128 78
Max. no. of send and receive bytes
(output/input)
128
*
78
The maximum number of receive bytes (input
bytes) also includes the diagnostics bytes of the
stations and of any local expansion modules
which are connected to the same line.
